The TIA (Television Interface Adapter) is a custom chip designed by Atari for
the 2600. It is the heart of the 2600 and responsible for the generation of
graphics and sound. Given that it's a custom chip and not off-the-shelf hardware
like everything else in the 2600, it is somewhat difficult to come by schematics
for it. However, Mark De Smet was able to get his hands on a set of hand-drawn
schematics, and scanned them in using a three foot wide scanner. There are five
sheets, each of which measures two feet by three feet, and as you can imagine
the resulting scans are quite large.

We have included two sets of scans here, one at 14400 x 9820 resolution, and
another set at 2048 x 1396. Be warned, the larger set of images requires a good
amount of memory to open up and manipulate in your favorite image viewer or
editor! If you'd like to purchase full "D" size copies of the original
schematics (which is where these scans originated), please contact AtariMuseum.com.
